Species
Pike (Esox lucius)
 |
Northern Pike Canada |
The pike species are native to the Palearctic and Nearctic ecozones, ranging across northern North America and from Western Europe to Siberia in Eurasia.
Pikes can grow to a maximum recorded length of 1.83 metres (6 ft), reaching a maximum recorded weight of 35 kilograms (77 lb). Individuals have been reported to reach 30 years in age. They have the elongated, torpedo-like form of predatory fishes, with sharply-pointed heads and sharp teeth. Their coloration is typically grey-green with a mottled or spotted appearance. The pike's marking is like a finger print, each with different patterns.
Bream (Abramis brama)
Bream are widespread in the Volga River, and are called Lesh (Лещ) in Russia. Bream mostly feed from the bottom of rivers and are fished with donkas, fishing rods that drop the hook and bait on the bottom of rivers and lakes.
Bream is not a scientific name, and is used to described fish of many different genera and families. The term sea bream is sometimes used for porgies (Sparidae) or pomfrets (Bramidae).

Roach (Rutilus rutilus)
The Roach (Rutilus rutilus, family Cyprinidae, plural also roach) is a small freshwater and brackish water fish native to most of Europe and western Asia. It is typically a small fish, reaching 35 cm long, rarely 45 cm, and weighing up to 1 kg, rarely 1.8 kg. It is very common and its flesh is often enjoyed as food.
- Name's origin: from Old French roche, possibly from Germanic.
- Description: It has an elongated tailfin with silver scales.
- Habitat: Often found in moving water, the roach likes depths of about 2 or 3 m; it also enjoys weedy waters.
- Behaviour: a gregarious fish that lives in schools; the bigger ones keep themselves somewhat apart from the others.
- Food: small molluscs, insect larvae, annelid worms, moss, algae, surface insects.
- Reproduction: from April to June or July when the water's temperature is at least 12°C, the female lays from 50,000 to 100,000 eggs. Roach grow slowly over a span of 2 or 3 years.
Tench (Tinca tinca)
The tench or doctor fish (Tinca tinca) is a fish of the Cyprinid family, and is one of the commonest and most widely spread freshwater fishes of Europe.
It thrives best in enclosed, preserved waters, with a clayey or muddy bottom and with an abundant vegetation; it avoids clear waters with stony ground, and is altogether absent from rapid streams. The tench is distinguished by its very small scales, which are deeply imbedded in a thick skin, whose surface is as slippery as that of an eel.
The largest Tench are often found in gravel pits, although equally at home in waters with a clayey or silty bottom where there is an abundance of vegetation; dislikes rapid streams. return to top «
Rudd (Scardinius erythrophthalmus)
The Rudd (Scardinius erythrophthalmus) is a small fish, a widespread member of the family Cyprinidae.
Morphologically, this species is very similar to the Roach (Rutilus rutilus), with which it can be easily confused. It can be identified by eye colour (deep blood-red as opposed to yellow) or counting the soft rays in the dorsal fin (8-9 compared to 10-12). Confusingly, these species can hybridise, producing intermediate forms. The rudd can also hybridise with the carp bream Abramis brama.
In New Zealand and Canada it is considered a pest fish due to impacts on native species.

Carp (Cyprinus carpio)
Carp is a common name for various freshwater fishes of the family Cyprinidae, a very large group of fishes that dominates the fish faunas of Eurasia and North America. Some consider all cyprinid fishes carps and the family Cyprinidae itself is often known as the carp family. In colloquial use, however, carp usually refers only to several larger cyprinid species such as Cyprinus carpio (common carp), Carassius carassius (Crucian carp), Ctenopharyngodon idella (grass carp), Hypophthalmichthys molitrix (silver carp), and Hypophthalmichthys nobilis (bighead carp). Carps have long been an important food fish to humans as well as popular ornamental fishes (see koi and goldfish). As a result, carps have been introduced to various locations where they are often considered pests
Perch (Perca fluvialtilis)
Perca is the genus of fish referred to as perch or yellow perch, a group of freshwater fish belonging to the family Percidae. Perch, of which there are three species in different geographical areas, lend their name to the largest order of vertebrates: the Perciformes, from the Greek perke meaning perch, and the Latin forma meaning shape. Many other species of fish are also called "perch."
Eel (Anguilla anguilla)
True eels (Anguilliformes) are an order of fish, which consists of 4 suborders, 19 families, 110 genera and 400 species. Most eels are predators.
The flat and transparent larva of the eel is called a leptocephalus. A young eel is called an elver.
Most eels prefer to dwell in shallow waters or hide at the bottom layer of the ocean, sometimes in holes. Only the Anguillidae family comes to fresh water to dwell there (not to breed). Some eels dwell in deep water (in case of family Synaphobranchidae, this comes to a depth of 4,000 m), or are active swimmers (the family Nemichthyidae - to the depth of 500 m).
